Don't forget this sentence from the Lieutenant Pack rulesheet.
Purchasing and Triggering Plot Cards wrote:
Each time he triggers a Plot card ability that requires him to "exhaust this card" or "Use this card", he must spend a number of threat tokens equal to the Plot card's TRIGER COST.
This means he (i.e. the OL) typically can't exhaust the card every turn because he won't have the Threat tokens to pay for it.
